Diagram 4-11C (Off-Grid mode) Min. grid-connected voltage: The acceptable low voltage point for solar inverter with grid connected. Max. grid-connected voltage: The acceptable high voltage point for solar inverter with grid connected. Min. grid-connected frequency: The acceptable low frequency point for solar inverter with grid connected. Max. grid-connected frequency: The acceptable high frequency point for solar inverter with grid connected. The waiting time before grid-connection: Max. grid-connected average voltage: When the average voltage is higher than this setting, it will be identified as the utility is abnormal. Max. feed-in grid power: Maximum power to feed-in to the grid. Feed-in power factor: setting range is -0.99~-0.90 and 0.90~1.00. Min. PV input voltage: The acceptable low voltage point for PV terminals when grid connection is established successfully. Max. PV input voltage: The acceptable high voltage point for PV terminals when grid connection is established successfully. Min. MPP voltage: The acceptable low voltage point from solar module. 35
Max. MPP voltage: The acceptable high voltage point from solar module. Max. charging current: The acceptable high charging current point. Max. AC charging current: The maximum acceptable charging current from AC. If this AC charging current is higher than max. charging current, max. charging current will be set up as real charging current. Bulk charging voltage (C.V. voltage): Please check battery spec to set up this figure. Floating charging voltage: Please check battery spec to set up this figure. The curve of Bulk charging voltage (C.V. voltage) and Floating charging voltage are listed as below: U Bulk Voltage Float Voltage Bulk Absorption Floating time I time Start LCD screen-saver after: The maximum duration time to activate LCD backlight. Battery cut-off discharging voltage when Grid is available: It s to set up battery cut-off discharge voltage when grid is available. Battery re-discharging voltage when Grid is available: It s to set up battery re-charging voltage when grid is available. Battery cut-off discharging voltage when Grid is unavailable: It s to set up battery cut-off discharging voltage when grid is not available. Battery re-discharging voltage when Grid is unavailable: It s to set up battery re-discharging voltage when grid is not available. Battery temperature compensation: It s to adjust charging voltage based on 2V/cell when battery temperature is changing between 0~50 C. All charging settings are based on 25 C. If setting battery temperature compensation as 5mV, charging voltage will be reduced by the following formula. (T-25) * (Battery voltage with serial connection / 2 ) * 5mV 36
For example, 3-phase inverter with 48VDC under 30 C environment. (30 25) * (48VDC / 2 V/cell ) * 5 mv = 600mV. Then, when battery temperature is higher 5 C, charging voltage will be reduced 600mV. Vice versa. Feeding grid power calibration: This adjustment allows to calibrate inverter output power to meet demand power for connected load and avoid overflow to the grid. Max. battery discharge current in hybrid mode: It allows to set up maximum battery discharge current in grid-tie and grid-tie with backup mode operation.
